Yes, it will be a problem if somebody will damage it with some heavy machine.

Try to plan a safe path, or bury it only in places where it could be damaged. If you have a river or brook, you could just drown fiber in it.

Really there is some cheap repair kits on market, and it could even work if you just align and fix two fibers ends in the way they will light into each other (did it once with toothpick and isolation tape :) ), but it is much better to weld it.

If you have electric poles to your farm and know electrician who is responsible for your area, try to talk with him. Pole mounts is cheap and you don't need them on every pole since fiber is lightweight and strong, if you make an agreement with electrician on putting fibre on his poles, it could be a good variant.
